This isn't any old freshman though. (Well hes a soph but he was inelgible so his IQs are still freshmen)

99 ath

70 LP (HIGH)

I'm dumping all i can into getting that LP up as fast as possible but my team (BYU Crum) lacks inside scoring (and scoring in general) and he'll be my only option.

Can I count on a freshman to give me 12-15 PPG on a decent shooting percentage?

It appears he could be your second best scorer after Spates and definitely your best low post scorer, mostly because of his high Ath.

Warfel's good speed and ballhandling might be an asset as well. Only concern is his stamina. As he tires quickly, so will his shooting percentage over the course of the game.

he can carry a mediocre team to mediocrity... but thats about it :( its really hard to lead teams with lp scorers in general, with a young guy like this, its even worse. if he was a per based scorer, you might have a shot...
